LM5161: The conditions to come back from standby mode.

Part Number: LM5161

Hi team,

 

Customer is facing the issues that the switching operation doesn’t come back from standby mode even if VCC exceeds the rising threshold 3.98V and EN/UVLO 1.24V.

Looking at 7.3.10 Enable / Undervoltage Lockout in the datasheet, LM5161 should begin nominal switching operation with the above condition.

 

Are there any conditions to come back from standby mode ?

 

Thank you and best regards,

Michiaki
